If I can put a plug in for BetUK…….
We don’t carry over negative balances for our sportsbook OR casino and we also don’t have a minimum balance requirement to receive payments.
We are a young sportsbook not like Bodog, but we do have a lot to give.
Get in touch if you want more details about our affiliates program or check it out at http://www.betuk.com/en/affiliates/index.html. : )
